Measurement of radioactivity in the environment — Guidelines for effective dose assessment using environmental monitoring data — Part 1: Planned and existing exposure situation (ISO 20043-1:2021)
These international guidelines are based on the assumption that monitoring of environmentalcomponents (atmosphere, water, soil and biota) as well as food quality ensure the protection ofhuman health[2][4][5][6][7][8]. The guidelines constitute a basis for the setting of national regulationsand standards, inter alia, for monitoring air, water and food in support of public health, specifically toprotect the public from ionizing radiation.This document provides— guidance to collect data needed for the assessment of human exposure to radionuclides naturallypresent or discharged by anthropogenic activities in the different environmental compartments(atmosphere, waters, soils, biological components) and food — guidance on the environmental characterization needed for the prospective and/ or retrospectivedose assessment methods of public exposure — guidance for staff in nuclear installations responsible for the preparation of radiological assessmentsin support of permit or authorization applications and national authorities’ officers in charge ofthe assessment of doses to the public for the purposes of determining gaseous or liquid effluentradioactive discharge authorizations — information for the public on the parameters used to conduct a dose assessment for any exposuresituations to a representative person/ population. It is important that the dose assessment processbe transparent, and that assumptions are clearly understood by stakeholders who can participatein, for example, the selection of habits of the representative person to be considered.Generic mathematical models used for the assessment of radiological human exposure are presentedto identify the parameters to monitor, in order to select, from the set of measurement results, the " bestestimates" of these parameter values. More complex models are often used that require the knowledgeof supplementary parameters.The reference and limit values are not included in this document.
